Divers Caught Cutting Internet Backbone Cable

What’s the least sophisticated, but probably the most foolproof, way to cut off a country’s Internet traffic? Literally cutting it by severing undersea Internet cables. That’s what the Egyptian navy caught three scuba divers doing in the waters 750 meters off the port city of Alexandria on Wednesday. The cable they were going after was the 18 000-kilometer-long South East Asia–Middle East–Western Europe 4 (SEA-ME-WE 4) line, the Internet backbone that carries data between Europe, Africa, the Indian subcontinent, and Malaysia and Singapore in southeast Asia.

Internet service in Egypt had already been off since 22 March, supposedly because a passing ship damaged a separate cable. The trio, who approached “hacking” from a different angle than usual, took to the water a day before repairs to the other cable were expected to be completed and service restored.

The effects of the ship taking out that cable were experienced as far away as Pakistan and India, Jim Cowie, chief technology officer at Renesys, a network security firm, told the Associated Press. Cowie noted that a severed cable can force wide scale data rerouting, with some of the packets traveling the long way around the world.

Ship anchors and propellers have been blamed for serious cable breakages in the Mediterranean that affected northern Africa. Perhaps this incident will cause investigators to cast a more jaundiced eye in future cases.

How the FCC Settles Radio-Spectrum Turf Wars

Remember the 5G-airport controversy? Here’s how such disputes play out

The airline and cellular-phone industries have been at loggerheads over the possibility that 5G transmissions from antennas such as this one, located at Los Angeles International Airport, could interfere with the radar altimeters used in aircraft.

You’ve no doubt seen the scary headlines: Will 5G Cause Planes to Crash? They appeared late last year, after the U.S. Federal Aviation Administration warned that new 5G services from AT&T and Verizon might interfere with the radar altimeters that airplane pilots rely on to land safely. Not true, said AT&T and Verizon, with the backing of the U.S. Federal Communications Commission, which had authorized 5G. The altimeters are safe, they maintained. Air travelers didn’t know what to believe.

Another recent FCC decision had also created a controversy about public safety: okaying Wi-Fi devices in a 6-gigahertz frequency band long used by point-to-point microwave systems to carry safety-critical data. The microwave operators predicted that the Wi-Fi devices would disrupt their systems; the Wi-Fi interests insisted they would not. (As an attorney, I represented a microwave-industry group in the ensuing legal dispute.)
